This paper studies the consensus problem for multi-agent systems. A distributed consensus algorithm is developed by constructing homogeneous pulse width modulators for agents in the network. In particular, a certain percentage of the sampling period named duty cycle is modulated according to some state difference with respect to the neighbors at each sampling instant. During each duty cycle, th...

This paper sprays five hybrid pulse width modulation strategies for three level inverters in FPGA platform. The proposed hybrid-modulation strategy is an amalgamation of fundamental-frequency modulation and any carrier based pulse width modulation (SPWM) invoking the performance of the well-known carrier based PWM modulations. The main philosophy of this modulation is the reduction of switching...

Unfortunately, traditional RF pulse measurements become less effective predictors of performance in radars that use pulse compression. For example, the width of an uncompressed radar pulse is directly related to spatial resolution. In contrast, the resolution depends on pulse width, chirp bandwidth and chirp linearity in a compressed radar system that uses linear frequency modulated (LFM) chirp...

In this paper a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. . The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. The fundamental component of the three-phase line-to-line voltage is increased by about 15 percent above than that of the conventional sine-wave inverter. The sinusoidal PWM switching scheme allo...

This paper proposes a single-phase five-level inverter with a modified pulse width-modulated (PWM)control scheme. The modified pulse width-modulation technique is developed to reduce switching loss.Also, the proposed multilevel inverter can reduce the requirement of power switches compared to aconventional cascaded multilevel inverter. The modes of operation, control signals, and operatingprinc...

We have proposed a novel driving concept for TFT-OLEDs, pulse-width modulation with current uniformization. This driving method can simultaneously achieve precise grayscale and exceedingly improve luminance uniformity. Lately, we succeeded to reduce the number of TFTs in a pixel circuit from nine to seven. Especially in this paper, its working and tolerance against characteristic deviations of ...

During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some specific applications, however, recently, these machines are becoming more used due to the powerful magnetic characteristic of the rare earth, being used in different areas. Several researchers have proposed implementations combining the use of permanent magnet synchronous motor with the direct torque cont...
